Powder Metallurgy Tooling Design and Machining Services

To address the challenges of stress concentration at corners and edges during demolding of square compacts, which can easily lead to internal cracks, our tooling adopts a composite structural design. Core components include the female die, upper punch, lower punch plate, outer die sleeve, and limiting sleeve. The advanced split-type female die design consists of four supporting plates assembled end-to-end, combined with a tapered outer die sleeve that is smaller at the top and larger at the bottom. During demolding, the female die and compact are pressed out together, avoiding direct application of enormous demolding resistance to the compact. This perfectly solves the demolding difficulties and internal crack defects caused by the lack of draft angles in square compacts. Core components are machined by skilled engineers with tolerances achievable to ±0.002mm.

Tooling Material Selection

Our tooling materials are preferentially made from SKD11 tool steel and powder metallurgy tooling steel, strengthened through vacuum hardening, deep cryogenic treatment, and precision grinding processes, achieving hardness of HRC58 to 62 with excellent compression resistance and wear resistance. Cavities are machined from integral forged blanks, ensuring sufficient die body rigidity. Dimensional tolerances are controlled within ±0.002mm, with squareness deviation less than or equal to 0.005mm, ensuring neat corners and uniform dimensions of finished products. Die surfaces are treated with mirror polishing and TiN coating to reduce powder adhesion and improve demolding smoothness. For powder compaction environments requiring high longevity and high-temperature resistance, tungsten carbide material is used to achieve extended service life.
